Pourable, addition-curing, two-component silicone rubber that vulcanizes at room temperature. Non-toxic, odorless, two-component liquid silicone rubber, are two-component materials.Resistance high temperature of 250℃, shrinkage rate lower than 0.1%.
Applications
Addition silicone rubbers can be applied to PU resin casting, general mold making, GRC and concrete molding, superior manual mold design, food grade molding application, rapid prototyping(urethane casting/ silicone tooling/ vacuum casting).
Features
• Almost nil shrinkage, cure at room temperature
• Low Shore A hardness (approx. 30)
• High tear strength
• Food grade silicone(environmental, odorless and nontoxic)
• High resistance to high temperature and aging(resist -60 to 250℃)
• High chemical resistance to aggressive components of some types of resins
• Outstanding resistance to common casting resins
Important note
The platinum catalyst is in component B. A and B components may only be used together if they have the same batch number. Addition silicone rubber can react with compounds such as phosphorus, ammonia, acid, mercaptan,it will produce harmful substances.
